I matched ported the t4 manifold and turbo on my truck now.
I just received my new stainless diesel manifold, the ports
are smaller then on my turbo, going by gasket. Are the any
reason to port this.
did you gasket match your turbo and manifold or port match? you usually want to port the exit a little smaller than the entrance unless you pin the items because gravity is going to allow the pieces to sag down a little and you'll have a lip
